Lamarkizam (ili Lamarckovo nasljeđivanje), ideja da organizam karakteristike koje je stekao za života može prenijeti na svoje potomstvo (znana kao i heritabilnost stečenih karakteristika ili mekano nasljeđivanje). Ime je dobio po francuskom biologu Jean-Baptisteu Lamarcku (1744. – 1829.), koji je inkorporirao djelovanje mekanog nasljeđivanja u svoje evolucijske teorije kao dodatak svojem konceptu inherentno progresivne tendencije koja tjera organizme stalno k većoj kompleksnosti, u paralelnim no odvojenim lozama bez ikakva izumiranja. Lamarck nije prvi osmislio ideju mekanog nasljeđivanja, koja predlaže da su individualni napori za života organizama glavni mehanizam koji goni vrste na adaptaciju, pri čemu bi oni navodno stekli adaptivne promjene i prenijeli ih na potomstvo.

Kada je Charles Darwin objavio svoju teoriju evolucije prirodnom selekcijom u O porijeklu vrsta, nastavio je davati povjerenje u ono što je nazivao "nasljeđivanjem uporabe i neuporabe", no odbacio je ostale aspekte Lamarckovih teorija. Poslije je Mendelova genetika nadomjestila zamisao nasljeđivanja stečenih crta što je naposljetku dovelo do razvoja moderne evolucijske sinteze i općeg napuštanja lamarkističke teorije evolucije u biologiji. Unatoč tomu napuštanju zanimanje za lamarkizam se nastavilo (2009.) kada su istraživanja na polju epigenetike rasvijetlila moguće nasljeđivanje bihevioralnih crta koje je stekla prethodna generacija.[1][2][3][4]
